1106 REF2 SELECT 0…17, 19…21 1 19 (PID1OUT)
Selects the signal source for external reference REF2.
0…17 – Same as for parameter 1103 REF1 SELECT.
19 = PID1OUT – The reference is taken from the PID1 output. See Group 40: PROCESS PID SET 1 and Group 41:
PROCESS PID SET 2.
20…21 – Same as for parameter 1103 REF1 SELECT.

1107 REF2 MIN 0.0…100.0% 0.1% 0.0%
(0.0…600.0% for toruqe)
Sets the minimum for external reference 2.
• The minimum analog input signal (in volts or amperes) corresponds to REF2 MIN in %.
• Parameter 1301 MINIMUM AI1 or 1304 MINIMUM AI2 sets the minimum analog input signal.
• This parameter sets the minimum frequency reference.
• The value is a percentage of the:
– maximum frequency or speed
– maximum process reference
– nominal torque.
1108 REF2 MAX 0.0…100.0% 0.1% 100.0%
(0.0…600.0% for torqe)
Sets the maximum for external reference 2.
• The maximum analog input signal (in volts or amperes) corresponds to REF2 MAX in %.
• Parameter 1302 MAXIMUM AI1 or 1305 MAXIMUM AI2 sets the maximum analog input signal.
• This parameter sets the maximum frequency reference.
• The value is a percentage of the:
– maximum frequency or speed
– maximum process reference
– nominal torque.
